wordpress: apply log_not_found more widely

The vast majority of /var/log/nginx/error.log is filled with this:

> open() "/srv/wordpress/sites/api_jquerymobile_com/gw-resources/api.jquerymobile.com/buttonMarkup/index.html"
> failed (2: No such file or directory),
>   client: XXX,
>   server: api.jquerymobile.com,
>   request: "GET /resources/buttonMarkup/index.html HTTP/1.1",
>   host: "api.jquerymobile.com"

> open() "/srv/wordpress/sites/jqueryui_com/gw-resources/jqueryui.com/demos/datepicker/datepicker-fr.js"
> failed (2: No such file or directory),
>   client: XXX,
>   server: jqueryui.com,
>   request: "GET /resources/demos/datepicker/datepicker-fr.js HTTP/1.1",
>   host: "jqueryui.com"
